SPREADlNG-ROLL FOR CORN HUSKERS AND SHREDDERS.

SPECIFICATION forming part of Letters Patent No. 754,158, dated March 8, 1904.

Application filed November 20, 1903. Serial No. 181,907. (No model.)

To wlZ w/wm it may concern:

Be it known that I, JULIAN H. PITKIN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Spreading-Rolls for Corn Huskers and Shredders, of which the following is a complete specification;

In the ordinary type of spiral spreadingrolls used on shredders it is found that a continuous spiral of uniform pitch will often result in forcing the stalks of corn too far laterally and otherwise irregularly distributing the same. The purpose of this invention is to overcome this difliculty which is accom plished by the use of zigzag-notched spirals instead of uniform spirals, the notches in the spirals enabling the stalks to be released from the grasp of the spiral flanges, and thus insuring a uniform disposition thereof.

Referring to the drawings, Figure 1 is an elevation of a portion of shredder, illustrating the arrangement of the spreading-roller relative to the adjacent cooperating parts. Fig. 2 is a plan View of that portion represented in Fig. 1. Fig. 3 is a longitudinal View -of the improved spreading-roller, and Fig. 4 is an end view of same. Figs. 5 and 6 represent sections forming the right and left hand spi rals, respectively.

In the drawings, A designates a portion of the main frame of a shredder; B, the huskingrolls; O, the shredding-head, and D the endless feeding-apron, the lower portion of which lies in a position parallel with and adjacent to the husking-rolls. The endless apron D is mounted upon the rollers d, d, d and 6Z3 and is driven, preferably, by means of a sprocketchain c, passing over the sprocket-wheels 6F and e on the roller d and the lower feedingroll E, respectively.

E designates the upper feeding-roll, which is yieldingly held in operative relation with respect to the roller E.

F represents the spreading-roll and is of a it is located.

ed upon the free ends of two vertically-vibratile arms G. Motion is communicated to the spreading-rollby means of a sprocketchain 9, passing around the sprocket-wheel f on the shaft of the spreading-roll F and over a sprocket-wheel g, the axis of which is colined) given to the flange on the spreadingroll.

In Fig. 3 will be seen that the roller F consists of a cylinder with a right and left hand spiral flange starting from the center and extending to either end. The spiral flanges consist of a series of plates or sections F, bolted or otherwise secured to the roll in a spiral form. These plates or sections consist of the flanged portion f, extending radially of the roll, and a web portion f, having a curvature corresponding to the surface thereof and to which it is" secured. The flange f extends in a direction oblique to the axis of the roll; but a portion, f of its length is made to extend transverse to said axis, the result being to provide momentary intervals of time in which no lateral movement will be given to the stalks of corn while under the spreading action of the roll, thus permitting the stalks which lie in the notches between the adjacent sections constituting the spiral to become disengaged and distributed evenly across the feedingapron. These notches (shown as f in Fig. 4) are formed by the receding edge of the flange portions f and f of the sections F.

What I claim as my invention, and desire to secure by Letters Patent, is

A spread ing-roll for corn huskers and shredders comprising a shaft and a series of plates or flanges bolted thereto, each individual plate ner as to form oppositely-pitched interrupted spirals about the said shaft, substantially as described.
